An apparatus and method for determining a physical parameter affecting an optical sensor or a number of sensors in a network. The apparatus uses a narrow linewidth source at an emission wavelength λand an arrangement for varying the emission wavelength λof the radiation. An analysis module with curve fitting is used to generate a fit to the response signal obtained from the optical sensor. The physical parameter is determined form the fit rather than from the response signal. The apparatus can be employed with Bragg gratings, etalons, Fabry Perot elements or other optical sensors.

Tunable external cavity lasers are used in applications such as interferometry, FM spectroscopy, and optical communications equipment testing. Mode hop free high bandwidth frequency modulation operation is desired in a tunable external cavity laser. This application describes new and novel techniques for controlling the output wavelength of a tunable external cavity laser while suppressing mode hop.

A laser-emitting device may be coupled to an electro-optically controlled wavelength actuator. An electro-optically controlled wavelength actuator may be a holographic wavelength actuator or a liquid crystal wavelength actuator. The electro-optically controlled wavelength actuator may function as a tunable diffraction grating for external cavity lasers.

Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter. In an optional aspect, the outer tubular structure further comprises a grasper to stabilize the catheter for receipt of the collapsible implant, and the internal diameter of the inner tubular structure varies to cause the grasper to first contract and stabilize the catheter, and then expand and release the catheter, as the grasper moves into the inner tubular structure.

A fluid distribution system comprising a table, an alignment stage, and a plurality of processing stations. The table can be configured to engage at least one of a plurality of microplates and can be movable at least in an X-axis direction. The alignment stage can be configured to move the table at least in a Y-axis direction that differs from the X-axis direction. The plurality of processing stations comprises at least one or more dispensing stations and a plate-handling station. Each of the one or more dispensing stations comprises a dispensing device adapted to dispense fluid into or onto one or more of a plurality of microplates, and the plate-handling station comprises a plate-handling device adapted to selectively pick up and deposit on the table individual microplates from a plurality of microplates, at least one at a time. Methods of preparing microplates are also provided as are systems and methods for tracking microplates during microplate preparation, methods of avoiding cross-contamination during microplate sample loading, and methods of dispensing fluids while preparing a plurality of microplates.
